Comando lshw

Comando lshw

Bom, quando queremos saber qual o Hardware noso equipamento tem para Windows usamos AIDA, EVEREST entre outros e no Linux como saber seu hardware, versão de Kernel, Barramentos entre outras informações, esse artigo vai mostrar tudo isso OK.

Usando o Terminal para Informação do Sistema

# lshw –help
Hardware Lister (lshw) – B.02.16
uso: lshw [-format] [-options …]
       lshw -version

    -version imprime a versão do programa (B.02.16)

formato pode ser
    -html           gera saída de árvore de hardware como HTML
    -xml            gera saída de árvore de hardware como XML
    -short          gera saída dos caminhos de hardware
    -businfo        gera saída de informações de barramento

opções podem ser
    -class CLASS    mostra somente uma classe de hardware
    -C CLASS        o mesmo que ‘-class CLASS’
    -c CLASS        o mesmo que ‘-class CLASS’
    -disable TESTE  desativa um teste (como pci, isapnp, cpuid, etc. )
    -enable TESTE    ativa um teste (como pci, isapnp, cpuid, etc. )
    -quiet          não exibe o status
    -sanitize       sanear saída (remove informações confidenciais como números de série, etc.)
    -numeric        gera saída de IDs numéricas (para PCI, USB, etc.)
